SWING CRYSTAL: Crystallization, Polymorph, Salt and Solubility Screening

The leading technology in overhead gravimetric dispensing / dosing (patented) combined with a wide range of crystallization plates, and our user-friendly software, allow you to standardize and accelerate your crystallization experiments.

Example Customer testimonial

The principal gain over manual crystallization lies in the automated sequencing of crystallization steps, including computer controlled dosing of liquids and solids.

Key Advantages:

  • Decrease in cost per sample up to 90+ %.
  • Increase in productivity by a factor of 10+.
  • Up to 192 crystallization experiments per run can be done on MTP based and other formats.
  • Wide range of workflows: salt, polymorph, co-crystal, solubility screening (incl. agitation, pH, temperature gradients, filtration, controlled evaporation).
  • Systematically investigate the influence of critical factors such as different solvents (eluotropic series), different concentrations, rate of evaporation, temperature, cooling rate, agitation on crystal structures.
  • Run two different crystallization workflows simultaneously.
  • Highly reliable and precise gravimetric dispensing tools for liquid and solid dispensing.
  • Reproducible results.
  • Different reactor sizes (from < 1 mL to 100 mL in disposable formats and up to 1’000 mL in high-output process development reactors) allow for screening and development / scale-up on the same platform.
  • Direct output on XRPD compatible glass plates (eliminating e.g. risk of crystal damage, cross contamination by electrostatic forces due to moving the powders).
  • Easy access to data with a convenient interface to pull results into Excel or virtually any other software.
  • Interface to DoE.
